1. 1. Distributed Immersive Participation : Realising Multi-Criteria Context-Centric Relationships on an Internet of Things

   Författare :Jamie Walters; Theo Kanter; Roch Glitho; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pervasive computing; ubiquitous computing; mediasense; context; context awareness; context centric; peer-to-peer; immersive participation; multi-criteria context; context proximity; context distance; evolving context; context-aware query languages; publish.subscribe; distributed context awareness; sensor information; context information; context models; context relationships; context relations; Computer and Systems Sciences; data- och systemvetenskap;

   Sammanfattning : Advances in Internet-of-Things integrate sensors and actuators in everyday items or even people transforming our society at an accelerated pace. This occurs in areas such as agriculture, logistics, transport, healthcare, and smart cities and has created new ways to interact with and experience entertainment, (serious) games, education, etc. LÄS MER

3. 2. Lessons Learned in Structural Health Monitoring of Bridges Using Advanced Sensor Technology

   Författare :Merit Enckell; Johan Silfwerbrand; Konrad Bergmeister; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Health Monitoring; Structural Health Monitoring System; bridges; sensor technology; emerging technology; fibre optics; fibre optic sensors concrete; creep; shrinkage; steel; distributed sensors; crack detection; Järnvägsgruppen - Infrastruktur; Järnvägsgruppen - Infrastruktur;

   Sammanfattning : Structural Health Monitoring (SHM) with emerging technologies like e.g. fibre optic sensors, lasers, radars, acoustic emission and Micro Electro Mechanical Systems (MEMS) made an entrance into the civil engineering field in last decades. Expansion of new technologies together with development in data communication benefited for rapid development. LÄS MER

4. 3. Identifying locally induced loads in hard rock tunnel linings by distributed optical fibre sensors

   Författare :August Jansson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Distributed optical fibre sensors; Structural health monitoring; Tunnel lining experiments;

   Sammanfattning : In an infrastructure system, tunnels enable fast means of transportation in impassable terrain or city areas. However, inspections and maintenance can be expensive due to long down time and, in hard rock tunnels, the complexity of the structure may lead to over designing. LÄS MER

5. 4. Distributed Road Grade Estimation for Heavy Duty Vehicles

   Författare :Per Sahlholm; Karl Henrik Johansson; Emilio Frazzoli; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automotive; estimation; distributed systems; automatic control; heavy duty vehicles; road grade; road maps; Automatic control; Reglerteknik;

   Sammanfattning : An increasing need for goods and passenger transportation drives continued worldwide growth in traffic. As traffic increases environmental concerns, traffic safety, and cost efficiency become ever more important. Advancements in microelectronics open the possibility to address these issues through new advanced driver assistance systems. LÄS MER

7. 5. State Estimation for Distributed and Hybrid Systems

   Författare :Peter Alriksson; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Joint Maximum a Posteriori Estimation; Sensor Networks; Distributed State Estimation; Networked Embedded Systems; Markov Jump Linear Systems; Sensor Scheduling;

   Sammanfattning : This thesis deals with two aspects of recursive state estimation: distributed estimation and estimation for hybrid systems. In the first part, an approximate distributed Kalman filter is developed. Nodes update their state estimates by linearly combining local measurements and estimates from their neighbors. LÄS MER
